Abstract
Modular printing apparatus wherein multiple central-impression presses may be linked to one another, either directly or through a perfecting assembly that reverses the facewise orientation of cut sheets. The presses each contain circuitry defining a signal and control path for the press and a plurality of electrical contacts that renders the path accessible and facilitates serial connection of the presses without disruption of the path. At least one of the presses includes a port for receiving connection to a controller, which thereby engages the signal path and, via the path, operates the presses independently or together as appropriate. The system includes a connector that is used to couple the electrical contacts of one press to those of the second press, thereby establishing a single, continuous signal and control path through both presses accessible to the controller. The system can accommodate a perfecting assembly that may be selectably engaged between the presses, and which thereby becomes a part of the system. The perfecting assembly includes circuitry defining a signal and control path for the assembly and sets of of electrical contacts capable of mating with the contacts…
